Snapdax, Apex of the Hunt wants to mutate so it can deal damage and gain you life
During design, all that was needed to transform a Werewolf was having two spells cast in the turn, even if one was cast by you and one by your opponent
For example, you could exile four cards illustrated by Zoltan Boros and one card illustrated by Zoltan Boros & Gabor Szikszai

Thats probably not good enough in other formats, but Commander is going to love it
Even though Jason has solved the aggro problem, with cheap, recurrable attackers, today it remains harder than I'd like to build a solid B/U control deck without falling back on crutches like Grave Titan or Wurmcoil Engine
